Investigating the effect of spacing on the effect of staggered-slip permeable spur dike on flow mitigation can provide a theoretical basis for the design of modern shore protection projects. The CCHE2D software was used to conduct a two-dimensional numerical simulation study of the solid flume model in the Xinqiman section of the Tarim River. And then the effect of different spacing on the water surface line, flow velocity and bed shear stress distribution in the upstream permeable spur dike area under the action of staggered-slab permeable spur dike was analyzed. When the relative dam length ratio is 0.21, and the inflow and dam length remain unchanged, the larger the spacing, the better the uniformity of flow and velocity behind the upstream permeable spur dike, and the lower the value of water level and shear stress in the riverbed. When the spacing is 5 times the effective dam length, the flow velocity, water level and riverbed shear stress behind the upstream permeable spur dike tend to be stable. The results of the study can improve the theory of flow mitigation effect in the action area of inserted permeable spur dike.
